Title:
POWER TRANSMISSION EQUIPMENT AND NON-CONTACT POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2015104164
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide power transmission equipment and a non-contact power transmission device capable of suitably detecting abnormality caused by the flow of an overcurrent in a switching element.SOLUTION: Power transmission equipment 11 of a non-contact power transmission device 10 includes: an AC power supply 12 for outputting AC power of a preset frequency; and a primary side coil 13a to which the AC power is input. The AC power supply 12 includes a DC/AC converter 12b for converting, when DC power is input, the DC power into AC power. Here, the power transmission equipment 11 includes: an abnormality determination unit 32 for determining to be abnormal when an instantaneous value of a drain current Id, which is a current flowing in a first switching element Q1, is greater than a threshold current value; and a variable threshold unit 45 for varying the threshold current value.
